A simulation study of a possible application of modern control theory is presented.The problem is to check and calibrate a VOR-station from a circling aircraft.An accurate position estimate of the circling aircraft is needed in order to calculate the errors in the received VOR-signals.The position estimate is here 4 Piece LAF Sectional obtained from an integrated navigation system using an inertial navigation system (INS), a laser range-finder, angle measurements on the laser line-of-sight, and barometer readings.The range and angle measurements are fed to a Kalman filter which estimates errors in the navigation system.
Simulation results show that Fan Shop - CFL - Jerseys satisfactory accuracy is obtained by this method.The paper presents a description of the proposed system, the simulation model used, simulation results and some sensitivity analysis.
